@Sharon1074 Mites and fleas, etc. cannot survive high heat, so just throwing linens, throw pillows, etc in a hot dryer, would destroy anything the dog might have been carrying. As far as the rest of the place, just vacuum really well, every nook and cranny. Parasites like that tend to stay on the animal, anyway. Mites, for instance, actually burrow under the skin, they don't just fall off the dog or prefer walking across the floor to being on the animal.
There are sprays you can buy at pet stores and even the grocery store aisle where pet supplies are sold designed to remove pet odors, but I have no experience with them. I've had dogs all my life, but never had a stinky one. 🙂
Bowls of plain white vinegar set around for a few hours neutralize odors as well.
And sometimes an unpleasant smell gets "stuck" in our brains. We think we still can smell it, but it's actually not there anymore. Maybe get someone else to go in and let you know if they can smell dirty dog or an unpleasant odor.
